From the induction mannered null entrance of the game sphere induction component

摘要

PROBLEM TO BE SOLVED: To improve the fact that wide space is required for placing game ball inducing members and efficiency of producing the game ball inducing members is not good.;SOLUTION: Opening portions 31c and 32c existing between a plurality of bar portions 31b and 32b cross-linked between parallel supports 31a and 32a are so formed as not to pass a game ball 40, bar portions 31b and 32b and opening portions 31c and 32c are opposed each other and a pair of ladder members 31 and 32 arranged at distance narrower than the diameter of the game ball 40 are placed. Since the ladder members 31 and 32 are arranged at distance narrower than the diameter of the game ball 40, the game ball 40 alternately collides with the bar portions 31b and 32b to reduce the speed. In addition, since a passage for the game ball 40 to pass may be formed only by arranging a pair of the ladder members, the structure is simple.;COPYRIGHT: (C)2002,JPO
